Objective To reveal the clinical characteristics of heterotopic pregnancy(HP)and enhance the understanding of its complexity.Methods A retrospective study was conducted among all 390 852 pregnant women who were treated in two tertiary hospitals of obstetrics and gynecology in Shanghai from Jan 2011 to May 2021.We screened and collected patients who were diagnosed as HP,and analyzed their clinical characteristics including menopause time,conception method,location of ectopic pregnancy(EP)and clinical manifestations.Results A total of 185 HP cases enrolled and 14 EP site rupture cases were recognized.Among the 185 cases,84.9%had their EP site in fallopian tube,12.4%were cornual HP.In vitro fertilization-embryo transfer(IVF-ET)ranked first in conception method with rate of 83.8%,followed by ovulation induction with rate of 10.3%and spontaneous conception ranked last with rate of 5.4%.Vaginal bleeding was appeared in 38.4%HP patients,21.1%patients experienced abdominal pain and 12.4%patients had vaginal bleeding complicated by abdominal pain.It is worth mentioning that,25.4%patients had no clinical manifestation.The incidence of EP site rupture was 7.6%.In 14 EP rupture cases,71.4%had abdominal pain as their first clinical manifestation.The post-operation live birth rate of EP site rupture patients was 78.6%,and abortion rate was 14.3%.Conclusion The clinical manifestations of HP are diverse.For patients with vaginal bleeding and abdominal pain,conception method is IVF-ET or ovulation induction,detailed and dynamic transvaginal ultrasound examination should be careful carried out in the uterus and adnexal areas.Patients with abdominal pain should be alert to EP site rupture and early intervention was needed.

"Solid-liquid excipients" co-production is one of the typical processing methods of excipients used from ancient times to the present day, and is widely applied in various processing schools and regional specialty varieties. This method significantly reduces the toxicity of traditional Chinese medicine(TCM), moderates medicinal properties, and enhances clinical efficacy. However, modern scientific research has given it limited attention, and many co-production methods of "solid-liquid excipients" have not been applied in production and practice. This paper reviewed the historical development of "solid-liquid excipients" co-production, outlined modern processing standards and methods in different processing schools, and further elaborated on the purposes and effects of this co-production method. This study is expected to provide references and evidence for further in-depth research, inheritance, innovation, and practical application.

Sleep deprivation has been shown to exacerbate pain sensitivity and may contribute to the onset of chronic pain, yet the precise neural mechanisms underlying this association remain elusive. In our study, we explored the contribution of cholinergic neurons within the medial habenula (MHb) to hyperalgesia induced by sleep deprivation in rats. Our findings indicate that the activity of MHb cholinergic neurons diminishes during sleep deprivation and that chemogenetic stimulation of these neurons can mitigate the results. Interestingly, we did not find a direct response of MHb cholinergic neurons to pain stimulation. Further investigation identified the interpeduncular nucleus (IPN) and the paraventricular nucleus of the thalamus (PVT) as key players in the pro-nociceptive effect of sleep deprivation. Stimulating the pathways connecting the MHb to the IPN and PVT alleviated the hyperalgesia. These results underscore the important role of MHb cholinergic neurons in modulating pain sensitivity linked to sleep deprivation, highlighting potential neural targets for mitigating sleep deprivation-induced hyperalgesia.

Alzheimer's disease (AD) is the most common neurodegenerative disease characterized by progressive cognitive impairment. The pathogenesis of AD is complex, and its susceptibility and development process are affected by age, genetic and epigenetic factors. Recent studies confirmed that gut microbiota (GM) might contribute to AD through a variety of pathways including hypothalamic pituitary adrenal axis and inflflammatory and immune processes. CM formula, herbs, and monomer enjoy unique advantages to treat and prevent AD. Hence, the purpose of this review is to outline the roles of GM and its core metabolites in the pathogenesis of AD. Research progress of CMs regarding the mechanisms of how they regulate GM to improve cognitive impairment of AD is also reviewed. The authors tried to explore new therapeutic strategies to AD based on the regulation of GM using CM.

The present study explored the effective approaches to realize the leading role of traditional Chinese medicine （TCM） in preventing diseases， the synergistic role in treating serious diseases， the core role in the rehabilitation of diseases and summarized the experience to provide feasible plans for the evaluation of other dominant diseases of TCM. To evaluate the effectiveness， safety， and economy of TCM in the treatment of ischemic stroke， encephalopathy project team of the China Center for Evidence-based Traditional Chinese Medicine（CCEBTCM） established an evaluation group to determine the work plan and complete the evaluation work. The concepts of the evaluation involved high-quality evidence， expert opinion survey， expert interview， and drug catalog. Under the guidance of clinical experts and methodologists， the evaluation work was completed in accordance with four steps， i.e.， plan making， data collection and data extraction， evidence synthesis and evaluation， and report writing with the rapid review method. Through the review of TCM and western medicine experts， the advantage of TCM in the treatment of ischemic stroke was positioned in the convalescence period with the predominant effects of improving the neurological function defect and improving the daily living ability. In the convalescence period of stroke， TCM treatment could improve post-stroke motor dysfunction， post-stroke cognitive impairment， consciousness disorder， swallowing disorder， aphasia， constipation， urinary function， diplopia， etc.， and the advantages of acupuncture， Chinese medicine， and traditional exercise were more prominent. In terms of safety， TCM treatment of ischemic stroke showed lower incidence of adverse reactions， fewer adverse events， and a milder degree of related symptoms. In terms of economic performance， the combined treatment of TCM and western medicine played a synergistic role and made the treatment cost more reasonable. Compared with conventional intervention， the integrated TCM and western medicine rehabilitation program showed more economic and social benefits.

Activation and inflammation of microglial correlate with progressive neuronal apoptosis in neurodegenerative disorders such as Parkinson’ s disease (PD). γ-Aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system, has recently been shown to play an inhibitory role in the immune system, but the mechanism is unclear. In this study, the results showed that LPS promoted the release of inflammatory factors in a dose-dependent manner compared with the control group (P<0. 01). Meanwhile, cell viability and cytotoxicity assays showed that the released inflammatory factors could induce the decline of SH-SY5Y cell viability. BV2 microglia cells were pretreated with GABA and Muscimol, a GABA

Objective:To investigate the effect of tetrandrine on transforming growth factor-β₁（TGF-β₁）stimulated MRC-5 cells. Method:Different concentrations of TGF-β₁ (0, 2.5, 5, 10, 20, 40 μg·L^-1) were applied to MRC-5 cells. Proliferation toxicity of TGF-β₁ to MRC-5 was detected by cell counting kit-8 (CCK-8) method. Detection of alpha smooth muscle actin (α-SMA) and Vimentin's expression levels in MRC-5 by Western blot. Detection of changes of collagen I(Col-I) and fibronectin (FN)'s expression levels in MRC-5 supernatants by enzyme linked immunosorbent assay(ELISA) kit. And the appropriate concentration of TGF-β₁ activated MRC-5 cells was screened. The appropriate concentration of TGF-β₁ and different concentrations of Tet (0, 2.5, 5, 10, 20, 40 μmol·L^-1) were applied to MRC-5 cells, and CCK-8 method was used to screen safe concentration again. Western blot was used to detect changes in α-SMA and Vimentin expression levels in MRC-5 cells, and ELISA method to detect changes in Col-I and FN in MRC-5 cell supernatant. Result:Compared with the blank group, 20，40 μg·L^-1 of TGF-β₁ had toxic effects on MRC-5 cells at 24 hours (P<0.05), and 10，20，40 μg·L^-1 of TGF-β₁ had toxic effects on MRC-5 cells at 48 h (P<0.05).When Tet is added for 24 h, the half inhibitory concentration (IC₅₀) value was 14.07 μmol·L^-1, and when cultured for 48 h, the IC₅₀ value was 7.51 μmol·L^-1. Compared with the blank group, the relative contents of α-SMA, FN and Col-I in the 5 μg·L^-1 of TGF-β₁ group were obviously increased (P<0.05), and the relative contents of Vimentin were significantly increased (P<0.01), and the relative contents of FN and Col-I, α-SMA and Vimentin in 10 μg·L^-1 group were significantly increased (P<0.01). 10 μg·L^-1 of TGF-β₁ was co-cultured with Tet at different concentrations. Compared with the TGF-β₁ group, the relative levels of α-SMA, Vimentin and FN in the 5 μmol·L^-1 of Tet group were significantly reduced (P<0.01), and the relative levels of Col-I were obviously reduced (P<0.05). In the Tet 10 μmol·L^-1 group, the relative contents of the α-SMA, Vimentin, FN and Col-I were significantly reduced (P<0.01). Conclusion:TGF-β₁ can increase the levels of Col-I, FN and other extracellular matrices in MRC-5 cells, and Tet can effectively inhibit the occurrence of this change. It is suggested that Tet may inhibit secreting extracellular matrix of fibroblasts in the formation of pulmonary fibrosis.
